[lldb-dev] Host::LaunchProcess vs. ProcessPlugin::DoLaunch

[Jean-Daniel Dupas]

Here is a discussion that may give you some answers:

For the record, I wrote a process plugin, and end-up not having to implements the Process:DoLaunch method at all.
On OS X, all processes are launched by the platform which then call DoAttach. So the Process::DoLaunch code path is never use.

What do I need to understand about the differences between these two codepaths to make sure I implement the two correctly?  And is there perhaps a way to refactor some of this code so that all of the process-spawning code lives in the same place, and the launch args are flexible enough to support all of the different use cases?
